Summary and Outlook
Distance learning support of EduNet Technical infrastructure that can be accessed by teachers and learners Enhanced and easy to use tools
– To/oL already used by other departments (e.g., chemistry) Multimedia-based content
– Virtual experiments
– Interactivity
Evaluation ... difficult, since current experience is very limited
Follow-up project together with University Hannover, TU Clausthal Improve and test tools Integrated asynchronous and synchronous tools (i.e., To/oL and MACS) Provide content for the diploma program information technology
